The Greens will always defend protections against hate speech, and resist any weakening of the Racial Discrimination Act.

Greens leader Dr Richard Di Natale said that we have a responsibility as leaders to protect the values of equality, diversity and multiculturalism that make our society so great.

"Malcolm Turnbull has an opportunity here to stand up for the values of inclusion and diversity that we all thought he believed in before he came under such unrelenting pressure from the far-right wing of his party.

The Australian Greens say they will keep standing with the community to protect Section 18C of the Racial Discrimination Act, in the face of revelations Prime Minister Turnbull promised yet another attempt at changing it to win his leadership coup over Tony Abbott.

"In his rush to become Prime Minister, Malcolm Turnbull sold out those who would face discrimination to secure power for himself. It's disgraceful," said Greens Leader Richard Di Natale.

"Once again the far Right of the Liberal Party is leading Malcolm Turnbull, instead of the other way around.

The Greens believe that everyone has the right to celebrate and express their cultural heritage and that all people, regardless of ethnicity, language, religion, culture or place of birth, have equal rights.

Diversity has built a society in Australia to be proud of. Countless Australians joined us from all over the world, and have contributed to making our nation great.
